WATER-COCK.

SPECIFICATION forming part of Letters Patent No. 376,129, dated January 10, 1888.

Application filed May 5, 1887. Serial No. 237,232.

To aZZ whom it may concern.-

Be it known that I, JAMES MILTON ANDER- soN, a citizen of the United States, residing at ful Improvements in \Vater-Gocks; and I do hereby declare the following to be a full, clear,

and exact description of the invention, such. as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to water-cocks, theobject of the invention being to'provide anovel construction of packing designed to'be located above the disehargenozzle of said cock and designed to prevent the liquid from escaping through the upper end of the cock, at which point the operating-handleis located.

A further object of the invention is to combine with a cock having a spherical valvea novel construction of stem for forcing said valve from its seat.

A further object of the invention is to provide improved means for supporting the spherical valve when water-pressure for any reason whatever is removed therefrom.

The invention consists in the features of construction and combinations of parts, herein-,

denoted by the same letters of reference.

Referring to the drawings, A represents the body ofthe faucet, which, as shown, is constructed in th reesections connected by threaded joints. I The lower section, B, is provided with a threaded shank or extension, a, and an interior chamber,b, which is narrowed, as at B, and is provided adjacent to said narrowed portion with lugs B of which there may be as many as desired, though three havebeen found to answer all purposes.

The central section, A, has an opening in its lower end, which opening is adapted to be closed by a spherical valve, preferably of rubber, which rests against a turned seat in A, and said valve, when water-pressure is removed (NO model.)

from it,is adapted to be supported by the lugs B", thus allowing air to pass the ball when the water is turned off. The central section, A,

has an eduction-opening in which is secured handle.

0 represents the packing, which is preferably of rubber. This packing is substantially bell shape in form and is provided at its lower end with an annular flange, 9. The packing rests upon the upper end of the central section, and its flange g is'clamped between the ledge or shoulde'rf and said upper edge of the central section, thereby holding the packing firrnl y and securely in place. The packing has projecting downwardly from its inner upperend an extension, 0, which has a passage, h, extending through it.

D represents avalvestem. This stem is provided near its lower end wit-h a circumferendiameter as the interior of the upper section,

but slightly smaller, so as to permit the free vertical movement of the stem.

G represents the ball as it is in the seat closed. For a slight distance below the flange j the stem is reduced, thus forming a shoulder, k. The said stem has its lower end passed-through the passage of the extension of the packing, and said extension tits in the reduced portion of the stem, the lower end of the extension resting on the shoulder of the stem and the upper end of the packing resting against the under face of the flangej, said packing, as clearly shown, supporting the stem in a raised position,so that it is normally in the position shown in Fig. 1.

E represents a double reversible cam which has a central opening, with asquare top in opening to receive the rounded upper end of the stem, said cam resting only on the top of the steni,thus avoiding friction on the stem.

In operati0n,when it is desired to open the cock to permit the how of water, the handle at the upper end of the cock is turned,tl1us1owering the cam E, which,bearing against the top of the stem D,lowers the stem,th us depressing the packing and removing valve from its seat. When the faucet is to be closed, it is thrown to its seat by the rubber and waterpressure, the handle is turned in the reverse direction, and the packing pressing against the under face of the flangej raises the stem.

It will be seen from the above description that by the construction described and illustrated a thoroughly effective cock is provided, .and one that is simple in its construction and cheap to manufacture.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a water-cock, the combination of a body portion having a valve-seat, a spherical valve adapted to engage said seat, a valve-stein adapted to operate the spherical valve, a bellshaped elastic packing located in the upper part of the body portion and provided upon its lower end with an annular flange and upon its upper end with an extension through which said stein extends, an annular flange upon said valve-sten1 adapted to rest upon the upper part or" said packing, and a cam loosely fitting in the upper part ofsaid body portion,provided with an aperture in itslower part which forms a bearing for the upper end of the valvestem, said cam being secured to the handle portion, whereby the cam, andhence the valve-stein, can be raised or lowered, substantially as set forth.

In testimony whereof I have affixcd my signaturein presence of two witnesses.

JAMES MILTON ANDERSON.
